Inch Standard

A sleeve for the shank of the drill to allow the cutting diameter to be increased.

Guideline for Selecting a JUST FIT SLEEVE

Desired = (Drillø+ Increase of JFS) + .005"
(Eg.) Desired diameter is 1.015" (oversize is taken as .005").

Oversize can vary due to the cutting conditions used, please use the above as a guideline.

Metric Standard

A sleeve for the shank of the drill to allow the cutting diameter to be increased.

Ordering the Just Fit Sleeve

  • Purchasing Method 1

Oversize can vary due to the cutting conditions used. Therefore it is recommended to purchase as a set.
When placing an order, please use the set order number. (5 sleeves/set)

  • Purchasing Method 2

It is possible to order individually. When placing an order, please use the individual order number .

Application of Just Fit Sleeve

  1. When inserting the drill into the side lock holder, aligin the V groove on the outer peripheral edge of the drill flange, as well as the round holes of the outer peripheral edge of the sleeve flange and the screws of the side lock holder for fixing the drill. (If the drill does not have a V groove, align the notch of the drill shank with the round holes of the sleeve.)

  2. Insert screws A of the side lock holder directly to the open window of the sleeve and fix the drill. Tighten screw B to a degree so as not to damage the sleeve.

Application of MVX Type Drill

Use on a Lathe

  1. The outer insert and machine X axis must be set parallel. The drill is designed that the center of the inner insert is 0-.006" lower when matching the drill center and the machine spindle center

*The inner insert may fracture if the center height of inner insert is higher than the machine X axis.

Use on a Lathe
  1. To adjust the hole diameter by off-setting the drill, please adjust to X axis plus direction (expanding direction of the hole diameter). Refer to the holder dimension list for the maximum adjustment rate of each holder.

*It is not recommended to adjust to X axis minus direction (reducing direction of the hole diameter) as the holder may interfere with the hole.

  1. When through hole drilling on a lathe the disc produced by the drill exiting the work material material may be expelled at high velocity. To reduce the possibility of injury or damage, a cover guard is highly recommended.
